If a line drawing is (1) created in OO draw with lines of thickness >0 and <0.43
mm, (2) than stored in a gallery scheme and (3) copied from the gallery back
into a drawing, the thickness of the lines appears reduced to 0.

Example:
1. create a line using Drawing toolbar -> Line command 
2. set the thickness of the line to 0.42 mm (Format -> Line -> Width)
3. a new Theme (e.g. dummy) is created in the gallery
4. the line is dragged into this Theme
5. the line is selected in the gallery
6. this selection is copied back into the drawing (Insert -> Copy)

-> The line thickness of the object thus created is very thin, thinner than the
source line and similar to the representation of 0-width lines (use eg 200% zoom
factor to see the difference - or print the resulting drawing).

If the thickness of the source line is >= 0.43 mm, the line-thickness in the
resulting object appears correct - similar to that of the source object. 

Note: this bug happens both with "Draw" and "Presentations" (impress). It was
already present in 2.0.0, but OK in the 1.x releases.
